REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^ IO3 



obviously so and more shining, black throughout, glabrous ; head 

 finely but strongly, rather sparsely punctate, the sinus broad and 

 shallow, the obtuse lobes unimpressed; prothorax fully one-half 

 wider than long, the sides broadly arcuate, strongly so and very 

 convergent anteriorly, becoming almost parallel basally, the sinus 

 shallow, two-thirds as wide as the base, the angles much rounded; 

 surface sparsely, extremely minutely punctate, more distinctly 

 though still finely and rather sparsely toward the sides, the bead 

 moderately fine ; scutellum moderate, broadly triangular; elytra 

 between two and three times as long as the prothorax, two-thirds 

 longer than wide, gradually ogival at apex; surface not quite 

 smooth, remotely and very finely punctate throughout, but little 

 more closely or distinctly so laterally; prosternum minutely, 

 sparsely punctate, the process margined almost to the tip, which is 

 obtusely rounded, the bead sometimes virtually entire ; hind femora 

 and abdomen remotely and minutely punctate. Length 10. 5-13. 7 

 mm. ; width 4.25-5.4 mm. San Francisco. A moderate series 

 taken by the writer but not received from other sources. 



viatica Esch. 



Form shorter, broader, more convex longitudinally, much more shin- 

 ing, not alutaceous anteriorly, glabrous, deep black ; head rather 

 sparsely, very finely punctate, the apical sinus narrower and rather 

 deeper, the antennae stouter ; prothorax a little more elongate, 

 evidently less than one-half wider than long as a rule, the sides 

 subsimilar though frequently subangulate at the middle, the api- 

 cal sinus similarly shallow and the angles well rounded; surface 

 polished, very minutely, sparsely punctulate, in general but little 

 less finely so laterally ; elytra much less elongate, more obtuse at 

 tip, barely one-half longer than wide, sparsely but less finely and 

 more strongly punctured than in viatica^ the punctures impressed ; 

 prosternum sparsely, very finely punctate, the process broad, ob- 

 tusely rounded at tip, the marginal bead rather fine, generally 

 extending almost to the apex but in some cases entire; hind 

 femora and abdomen minutely, remotely and scarcely distinctly 

 punctulate. Length 11. 5-12. 7 mm.; width 4.9-5.S mm. Cali- 

 fornia. Cab. Levette lucidula n. sp. 



Form rather less slender than in viatica^ larger in size, blacK, the 

 under surface and legs piceous or rufescent, shining, the anterior 

 parts somewhat alutaceous, glabrous ; head very finely, sparsely 

 punctate, the apex rather broadly sinuate in circular arc, the 

 lobes obtusely rounded, not impressed ; prothorax barely one- 

 half wider than long, somewhat conical, the sides very feebly 

 and subevenly arcuate from base to apex, becoming parallel only 

 very near the base, the apical sinus shallow, three-fifths as wide 

 as the base, the angles obtuse and moderately rounded; surface 

 sparsely, extremely minutely punctate, more distinctly but still 

 sparsely and very finely so laterally, the marginal bead moderate ; 

 elytra about two and a third times as long as the prothorax, 

 parallel, gradually ogival behind; surface nearly smooth, finely,
